The 6CIT is a brief weighted cognitive screening tool used in primary and acute care settings. It samples orientation, attention, and memory recall in a short format. Scores range from 0 to 28, with higher values indicating greater cognitive impairment signal.
Formula: Weighted total score, range 0-28 (higher scores indicate more impairment signal).

The 6-Item Cognitive Impairment Test (6CIT), developed by Katzman et al. and later adapted by Brooke and Bullock for UK primary care, consists of 6 items: (1) What year is it? (2) What month is it? (3) Give the patient an address to remember: John Brown, 42 West Street, Bedford. Ask them to repeat it immediately (maximum 3 attempts). (4) Count backwards from 20 to 1. (5) Say the months of the year in reverse order (from December back to January). (6) Recall the address given in item 3. The test is administered verbally by the clinician and scored after completion. Each item is scored based on the number of errors or the number of prompts required.
6CIT uses a weighted error scoring system: (1) Year orientation: 0 points if correct, 4 points if incorrect. (2) Month orientation: 0 points if correct, 3 points if incorrect. (3) Address recall learning: 0 points for successful registration; additional points if multiple prompts required (up to 3 points). (4) Count backwards 20-1: 0 points if no errors, 2 points for 1 error, 4 points for 2+ errors. (5) Months in reverse: 0 points if no errors, 2 points for 1 error, 4 points for 2+ errors. (6) Address recall at end: 0 if correct, up to 10 points for incomplete recall (2 points per element recalled incorrectly: name, number, street, town — 5 elements total). 6CIT total score range: 0-28. Lower scores indicate better performance. Higher scores indicate greater cognitive impairment.
6CIT score interpretation: 0-7 = Normal cognitive performance — no specific action required; standard monitoring. 8-9 = Borderline range — reassess with comprehensive cognitive evaluation, consider repeat assessment in 6 months. 10-28 = Probable cognitive impairment — comprehensive cognitive and functional assessment indicated; formal dementia workup (history, examination, labs, neuroimaging as appropriate). The original UK primary care validation (Brooke and Bullock, 1999) used a cutoff of 7/8 for sensitivity 78%, specificity 100%. For primary care case finding with higher sensitivity, a cutoff of 10 or above maintains specificity while detecting more cases. Document score and indicate the clinical action triggered.
General practitioners, primary care physicians, practice nurses, community health workers
The 6CIT's 5-7 minute administration time and simple verbal format make it one of the most practical dementia screening tools for busy primary care settings. Unlike MoCA (which requires printed materials and takes 10-15 minutes), 6CIT requires no materials and can be administered during a routine clinic appointment. It is widely embedded in UK general practice quality improvement frameworks (previously in the NHS Quality and Outcomes Framework for dementia case finding). 6CIT of 8 or above in a primary care consultation triggers a planned comprehensive dementia evaluation appointment.
Emergency physicians, emergency nurses, acute medicine teams, triage nurses
6CIT is used in emergency departments and acute medical units as a rapid cognitive screen for older adults presenting with acute illness. Cognitive impairment is found in 30-40% of older adult ED presentations and is frequently unrecognized. The 5-7 minute 6CIT can be administered by nursing triage staff without materials. 6CIT of 8 or above in the ED triggers: delirium assessment (CAM or 4AT), medication reconciliation review, capacity assessment documentation, and discharge planning modification (cognitive impairment affects safe discharge threshold).
UK general practitioners, practice nurses, NHS memory services
6CIT has been one of the most widely used cognitive screening tools in the NHS for dementia case finding in high-risk populations (patients with diabetes, cardiovascular disease, down syndrome). Previous NHS Quality and Outcomes Framework (QOF) indicators supported 6CIT use for annual cognitive health checks in at-risk older adult populations. 6CIT of 8 or above triggers direct referral to a local memory service under the NICE dementia pathway. The 6CIT's UK development and validation makes it particularly well-calibrated for UK primary care population use.
Anesthesiologists, surgical teams, pre-operative assessment nurses, perioperative medicine teams
Pre-operative cognitive assessment in older adults identifies patients at elevated risk for post-operative delirium and post-operative cognitive dysfunction (POCD). 6CIT in pre-operative assessment clinics provides rapid cognitive screening before elective procedures. 6CIT of 8 or above is a risk factor for post-operative delirium and prompts: anesthetic technique review (regional vs general), post-operative monitoring protocol activation, family communication about delirium risk, and enhanced post-operative cognitive recovery support.
Telephone triage nurses, remote healthcare providers, telehealth services
6CIT's verbal-only format (no written or visual materials required) makes it uniquely suitable for telephone cognitive screening — unlike MMSE (which has written components) or MoCA (which requires visual stimuli). 6CIT administered by telephone achieves acceptable psychometric performance for case finding. This property has made 6CIT valuable for: telephone pre-screening before memory clinic referrals, remote annual cognitive health checks, and telephone follow-up of patients with established mild cognitive impairment.
Care home managers, nursing home nurses, care home registered nurses
6CIT at care home admission provides rapid direct cognitive screening to complement informant-based tools (AD8, IQCODE). The 5-7 minute administration requires no materials and can be performed by any trained registered nurse. 6CIT of 8 or above at admission documents cognitive impairment as a baseline for care planning, behavioral management approach, communication strategy, and capacity assessment documentation. Serial 6CIT at quarterly review intervals can detect cognitive deterioration requiring care plan review.
The address registration component of 6CIT allows up to 3 repetitions. Record exactly how many repetitions were needed for the patient to repeat the address correctly — this learning efficiency data provides additional clinical information. Patients who need 3 repetitions to register an address have significantly worse delayed recall than patients who register it in 1 repetition, even if both groups recall the address successfully at the end. Some 6CIT scoring protocols incorporate the number of learning trials as an item score.
Score each 6CIT item as it is completed, not retrospectively at the end of the consultation. The weighted scoring system is specific — number of errors on counting backwards, number of months incorrectly recalled in reverse order, and number of address elements recalled correctly all require careful tracking. Retrospective recall of patient responses introduces scoring errors. Consider using a printed 6CIT scoring form to record responses as they occur.
The delayed address recall component (item 6) is weighted up to 10 points out of the 6CIT maximum of 28 points — making it the single most influential item. The address has 5 scorable elements (first name, surname, house number, street name, town name). For each element incorrectly recalled at the end of the test, 2 points are added. Meticulous recording of which specific address elements the patient recalls (or fails to recall) is essential for accurate 6CIT scoring.
Like MMSE, 6CIT includes items that require formal education-related skills: counting backwards and recalling months in reverse order are more affected by educational attainment than dementia-pure items. Patients with limited formal education (less than primary school) may score higher (worse) on 6CIT due to education effects rather than true dementia. In low-education populations, use IQCODE or AD8 (informant-based tools) as complementary measures, and interpret 6CIT borderline scores with explicit consideration of educational attainment.
Acute anxiety, depression, and medical illness (fever, pain, metabolic disturbance) can impair 6CIT performance independently of dementia. A 6CIT score of 8-12 during an acute illness presentation may represent cognitive effects of acute illness rather than underlying dementia. When 6CIT is elevated in the context of acute illness, document this context and plan reassessment when the patient has recovered from the acute illness (typically 4-6 weeks after acute illness resolution).
The classic 6CIT address (John Brown, 42 West Street, Bedford) is validated for UK populations. For non-UK settings, a culturally appropriate address with similar structure (first name, surname, house number, street name, town name) can be substituted. The address should be: culturally plausible, not associated with famous landmarks or well-known addresses, and consistent across all patients in a clinical setting. Consistency in address choice is essential for intra-setting comparisons and serial monitoring.
6CIT has longstanding validation in primary-care usage and later diagnostic-accuracy studies across memory and acute-care settings.
Higher 6CIT scores indicate greater cognitive concern and support more detailed diagnostic follow-up.
Use as a rapid first-pass cognitive screen in older adults when brief bedside screening is needed.
Performance can be influenced by education, language, sensory deficits, and acute illness; it is not a standalone diagnostic test.
